Function:
Invalidates and frees the offscreen caches of all image representations.Notes:
If you modify an image representation, you must send a recache message to the corresponding image object to force the changes to be recached. The next time any image representation is drawn, it is asked to recreate its cached image. If you do not send this message, the image representation may use the old cache data. This method simply clears the cached image data; it does not delete the NSCachedImageRep objects associated with any image representations.
If you do not plan to use an image again right away, you can free its caches to reduce the amount of memory consumed by your program.

Function:
Registers the image under the specified name.Notes:
Returns true if the receiver was successfully registered with the given name; otherwise, false.

Discussion
If the receiver is already registered under a different name, this method unregisters the other name. If a different image is registered under the name specified in aString, this method does nothing and returns false.

When naming an image using this method, it is convention not to include filename extensions in the names you specify. That way, you can easily distinguish between images you have named explicitly and those you want to load from the application's bundle. For information about the rules used to search for images, see the imageNamed method.

Function:
Sets the width and height of the image.Notes:
Pass the new size of the image, measured in points.

Discussion:
The size of an NSImage object must be set before it can be used. If the size of the image hasn't already been set when an image representation is added, the size is taken from the image representation's data. For EPS images, the size is taken from the image's bounding box. For TIFF images, the size is taken from the ImageLength and ImageWidth attributes.

Changing the size of an NSImage after it has been used effectively resizes the image. Changing the size invalidates all its caches and frees them. When the image is next composited, the selected representation will draw itself in an offscreen window to recreate the cache.

Function:
Returns a string containing TIFF data for all of the image representations in the receiver.Notes:
A string containing the TIFF data, or nil if the TIFF data could not be created.

Discussion:
You can use the returned data object to write the TIFF data to a file. For each image representation, this method uses the TIFF compression option associated with that representation or NSTIFFCompressionNone, if no option is set.

If one of the receiver's image representations does not support the creation of TIFF data natively (PDF and EPS images, for example), this method creates the TIFF data from that representation's cached content.

Notes:
A string containing the TIFF data, or nil if the TIFF data could not be created.

Function:
Returns a string containing TIFF data for all of the image representations in the receiver.Notes:
comp: The type of compression to use. For a list of values, see the constants in NSBitmapImageRep.

Returns a string containing the TIFF data, or nil if the TIFF data could not be created.

Discussion:
You can use the returned data object to write the TIFF data to a file. If the specified compression isn't applicable, no compression is used. If a problem is encountered during generation of the TIFF data, this method may raise an exception.
